Example Embodiment

[0038] Example one, combined with Figure 1-18 , A special measuring device for architectural design, including a box body 1 with an open lower end, the box body 1 opening downwards, characterized in that the lower end of the box body 1 is provided with four sets of wheels 2 that can be retracted into the box body 1. The wheels 2 are arranged in two horizontal and vertical rows. The box 1 is equipped with a shrinking device, and the box 1 shrinking device is connected to the wheel 2, so that the wheel 2 is driven by the shrinking device to shrink into the box 1. The device connects the wheel 2 and the box 1 together. The specific structure of the shrinking device will be described in detail in the following embodiments, but the shrinking device must be able to shrink the wheel 2 into the box 1. When carrying it, The wheels 2 are retracted into the box 1 by the shrinking device, which is convenient to carry. The two sets of wheels 2 on the same side are connected to the first motor 3 coaxially via a belt drive. The output shaft of the first motor 3 cannot be directly installed on the wheel 2 On the rotating shaft of the first motor 3, the sleeve pulley can transmit the power of the output shaft of the first motor 3 to the rotating shaft on the wheels 2. The first motor 3 is connected to the controller, and the controller can control the power of the first motor 3. The direction of rotation is the period of rotation, because in the measurement, the first motor 3 needs to rotate for a certain distance and then stop, and then rotate and drive the wheel 2 to rotate and walk;
[0039] The upper end of the box 1 is rotatably connected to a main shaft 4, the main shaft 4 is connected to a power device, and the power device is connected to a controller. The power device provides power input for the main shaft 4, and the controller controls the power device to drive the rotation direction and rotation of the main shaft 4 Itinerary, the power unit here can be controlled by humans or intelligently. If it needs to be controlled by humans, an infrared sensor should be added to the power unit to be controlled by the infrared remote control used by the user. The spindle 4 Four sets of quill shafts 5 rotatably connected to the upper end of the box body 1 are evenly distributed in the circumferential direction. The quill shafts 5 are arranged as far as possible. The upper end of the quill shaft 5 is vertically slidingly fitted with a telescopic rod 6 and To meet the requirement of non-disengagement, the telescopic rod 6 at the upper end of the quill shaft 5 is coaxially connected with it, and a limit ring is arranged at the upper end of the quill shaft 5, and the lower end of the telescopic rod 6 is matched with a limit circular table which cooperates with the limit ring, When the telescopic rod 6 moves to the extreme position in the vertical direction, it does not disengage from the sleeve shaft 5. The upper ends of the four groups of telescopic rods 6 are connected to a supporting plate 7, and the supporting plate 7 functions as a transitional support. The upper end thread inside 4 is fitted with a first screw 8. The upper end of the first screw 8 is connected to the supporting plate 7. When the main shaft 4 rotates, the supporting plate 7 is restricted by the four sets of telescopic rods 6 and cannot rotate. When the support plate 7 moves in the vertical direction, at the same time, due to the vertical sliding fit between the telescopic rod 6 and the sleeve shaft 5, the support plate 7 does not affect the vertical movement. The upper end of the support plate 7 is evenly connected with four groups of hydraulic cylinders 9, and the upper end of the hydraulic cylinder 9 is connected with a hydraulic push rod 10, and the hydraulic cylinder 9 is connected with a controller. The controller can control the work of the hydraulic cylinder 9 to accurately The upper end of the hydraulic push rod 10 is controlled by the rising distance to achieve balance. The upper end of the hydraulic push rod 10 is hinged with a connecting block 11, and the connecting block 11 is slidably fitted in the horizontally arranged balance platform 12, and satisfies the requirements The two sets of sliding blocks arranged in the longitudinal direction only move horizontally or longitudinally with respect to the balance platform 12. The connecting block 11 is slidingly fitted on the lower end surface of the balance platform 12. The cross section of the connecting block 11 is "T", and the balance The lower end of the table 12 is provided with a "T"-shaped chute, so that the corresponding sliding block only moves in the transverse or longitudinal direction where it is located. It should be noted here that it is in the transverse direction. The two sets of connecting blocks 11 only move in the transverse direction, and the two sets of connections in the longitudinal direction only move in the longitudinal direction. The cooperation between the chute and the connecting block 11 here is for the hydraulic push rod 10 to move vertically. When moving in the straight direction, there is a margin for adjustment to facilitate adjustment;
[0040] In the balance platform 12, there are two sets of slideways 13 intersecting in the transverse and longitudinal directions in a cross. The transverse slideways 13 and the longitudinal slideways 13 are arranged at intervals along the vertical direction, that is, The two sets of slides 13 cross each other with their centers on the same vertical straight line, but they are not on the same horizontal plane. The two sets of slides 13 are spaced in the vertical direction. The upper end is provided with a receiving groove 14, which is communicated with the slideway 13, and the receiving groove 14 is arranged at the center of the slideway 13. The upper end of the receiving groove 14 is connected to an electromagnetic chuck 15, which is connected to a controller, so The lower end of the electromagnetic chuck 15 is provided with a driving ball 16, and the lower end of the electromagnetic chuck 15 is in the shape of a chuck arc. When the device is not working, the electromagnetic chuck 15 has a channel to force the driving ball 16 to be adsorbed on its lower end. It can be well confined in the arc-shaped chuck. After the device reaches the measuring station, the controller will control the electromagnetic chuck 15 to power off, so that the driving ball 16 is separated from the electromagnetic chuck 15. It should be noted that the electromagnetic chuck The height of 15 should satisfy that after it is energized, the drive ball 16 can be perfectly adsorbed on the electromagnetic chuck 15. The two side walls of the containing groove 14 along the direction of the respective slideway 13 are provided along the other slideway 13 direction. The extended arc-shaped groove 17, that is to say, taking the horizontal slideway 13 as an example, the horizontal sides of the receiving groove 14 of the horizontal slideway 13 are provided with arc-shaped grooves 17 extending in the longitudinal direction. The cross-section is arc, and the arc groove 17 is arranged below the side wall. In the arc groove 17 along the direction of the other slide 13 is arranged two sets of vertically spaced conductive rods 18 to meet the requirements of driving the ball. 16 is in contact with the two sets of conductive rods 18 to conduct electricity. Below we all take the horizontal slide 13 as an example. The configuration of the vertical slide 13 is the same as that of the horizontal slide 13, and the arc groove of the horizontal slide 13 17 Two sets of conductive rods 18 extending in the longitudinal direction are arranged at intervals along the longitudinal direction, where the conductive rods 18 are box-connected, and the two sets of conductive rods 18 in the same arc groove 17 of the same group are Installed in the same series circuit, and then connect the series circuit formed by the two conductive rods 18 of the two arc-shaped slots 17 in parallel in a circuit. This circuit is connected with an electromagnet 23 to provide current for the electromagnet 23, that is, two The conductive rod 18 in the arc slot 17 on the side, as long as one set of conductive rods 18 is triggered, the electromagnet 23 will start to work, but if two sets of conductive rods 18 are required to be energized, the ball 16 needs to be driven to roll to the arc slot 17 Inside, the two sets of vertically arranged conductive rods 18 are connected to instantaneously energize the electromagnet 23. The electromagnet 23 works. As the driving ball 16 separates from the arc groove 17 due to gravity, the two conductive rods 18 is in a state of power separation, the electromagnet 23 is energized, and the slideway 13 is connected with two sets of guide rods 19 extending along the direction of the slideway 13 and arranged at intervals. The two sets of guide rods 19 extend transversely and are arranged at intervals along the longitudinal direction. , The slideway 13 is connected with two sets of slideways 1 The first spring 20 is arranged in three directions. The two ends of the first spring 20 are respectively connected with the drive plate 21 that is slidably engaged with the guide rail. The two sets of first springs 20 are arranged at the two ends of the slideway 13, but slide The middle position of the lane 13 needs to be set aside to ensure that the driving ball 16 can fall into the slide lane 13. The lower end of the middle portion of the slide lane 13 is provided with a rectangular groove 22, and the two sets of first springs 20 face the center of the slide lane 13. The driving boards 21 on the sides are respectively flush with the side walls of the rectangular slot 22. An electromagnet 23 is connected to the bottom surface of the rectangular slot 22. The electromagnet 23 is connected to the controller. The parallel circuit composed of conductive rods 18 is connected, no matter the conductive rod 18 circuit on either side of the lateral side is triggered, it will trigger the electromagnet 23 here to be energized, and the upper end of the electromagnet 23 is connected vertically A non-conductive second spring 24. The upper end of the second spring 24 is connected to a conductive arc-shaped plate 25. The upper ends of the arc-shaped plate 25 are in contact with the guide rod 19 respectively. In the initial position , The arc-shaped plate 25 and the guide rod 19 are in contact with each other. Taking the transverse slide 13 as an example, the arc-shaped plate 25 with an arc-shaped cross-section is arranged with the arc face down, and the upper ends of the arc-shaped plate 25 are respectively matched with the guide rod 19 , The purpose is to form an energized circuit. Once the electromagnet 23 is energized, the arc plate 25 is instantly attracted by the electromagnet 23 and moves downwards. The arc plates 25 are respectively connected along the two ends of the slideway 13 where they are located. There are two sets of outer ratchet wheels 26. The two sets of outer ratchet wheels 26 are arranged at intervals in the horizontal direction along the vertical direction of the slide 13 where they are located and connected coaxially. The horizontal ends of the arc-shaped plate 25 are longitudinally connected with two sets at intervals. The outer ratchet 26 is mounted on a longitudinally extending shaft extending from the end of the arc-shaped plate 25. A damping sleeve 27 is sleeved between the outer ratchet 26 and the shaft on which it is located. Between the outer ratchet 26 and the shaft When there is relative rotation between the two, it will provide a certain amount of damping, but the sum of the damping force here should be less than the restoring force of the second spring 24, otherwise the arc-shaped plate 25 cannot be reset. The outer gear ring 28 is rotated and sleeved on the outer side of the outer ratchet wheel 26, and the two can rotate relative to each other. The outer gear ring 28 is connected with an inner pawl 29 that matches the outer ratchet wheel 26. The outer ratchet wheel 26 and the inner pawl 29 constitute a ratchet-pawl structure. The outer gear ring 28 meshes with the rack 30 provided on the side wall of the rectangular groove 22 where it is located. The teeth of the outer gear ring 28 and the rack 30 meshes and rotates, and a rack 30 is opened on the side wall of the rectangular slot 22. When the electromagnet 23 is energized to attract the arc-shaped plate 25 and moves downward, the rack 30 and the outer ring gear 28 mesh, and the outer ratchet The ratchet-pawl structure formed by 26 and the inner pawl 29 is in an idling state, that is to say, the outer gear ring 28 does not drive the outer ratchet wheel 26 to rotate at this time, and the outer gear ring 28 is idling. After the power is completed, the second spring Under the action of 24, the arc-shaped plate 25 moves upward, and at this time, the outer gear ring 28 is driven by the ratchet-pawl transmission cooperation. The outer ratchet wheel 26 rotates. Due to the presence of the damping sleeve 27, the arc-shaped plate 25 will rise slowly during the ascent process, and will not reach the initial position instantaneously. The longitudinal sides of the rectangular slot 22 are provided with vertical lengths. The two ends of the arc-shaped plate 25 are constrained in the long holes, so that they can only move in the vertical direction. The two ends of the slideway 13 are connected with piezoelectric sensors 31. The piezoelectric sensor 31 is connected to the controller, and the hydraulic cylinder 9 on the corresponding side is driven by the controller to work. When a lateral or longitudinal tilt occurs, when the driving ball 16 is released and tilted, the piezoelectric sensor on the corresponding side will be triggered 31. Then the hydraulic cylinder 9 on the corresponding side is driven by the controller to work until the driving ball 16 returns to the middle position;
[0041] The area where the guide rod 19 matches the arc plate 25 is made of conductive material, and the box body 1 is provided with a buzzer 32. The buzzer 32 is connected to the guide rods in the two sets of slides 13 19 is electrically connected to the arc-shaped plate 25 to meet the requirements of electrical conduction between the guide rods 19 and the arc-shaped plate 25 in the two sets of slideways 13 before the buzzer 32 starts to work. Here, the middle conductive part of the guide rod 19 It will form an energized circuit with the arc plate 25 and the driving ball 16, that is, as long as the three are in contact with each other, the circuit will be conducted at this time, that is, the position of the driving ball 16 is in the middle of the guide rod 19 For the part with conductive material, the arc-shaped plate 25 is in contact with the middle part of the guide rod 19, and the circuit composed of the three will be conducted at this time, and only the three in the horizontal slide 13 and the vertical slide 13 are composed The buzzer 32 is turned on at the same time, and the buzzer 32 starts to work. The circuit settings here are easy to implement for those skilled in the art. I will not repeat them here. The buzzer 32 is activated. Figure 18 , The horizontal switch and the vertical switch respectively indicate that the guide rod, drive ball, and arc plate in the horizontal channel and the vertical channel form a circuit loop, which causes the point to be turned on. At this time, the horizontal switch or the switch in the longitudinal channel is turned on, only The circuits in both are turned on, and the buzzer starts to work, indicating that the balance table 12 is in the balance position at this time, and the surface can be measured at this time to ensure the accuracy of the measurement;
[0042] A measuring instrument is placed on the balance table 12, and the measuring instrument here can be a distance meter, an angle meter, etc.

Example Embodiment

[0043] The second embodiment, on the basis of the first embodiment, combined with the attached Figure 1-18 , The main shaft 4 is coaxially connected with a first gear 33, the first gear 33 is evenly meshed with a second gear 34 in the circumferential direction, the radius of the first gear 33 is larger than the second gear 34, the second gear 34 is vertically and coaxially slidably connected to the quill shaft 5 via a key. The quill shaft 5 is provided with a key along the vertical direction. The second gear 34 is provided with a key groove. The two cooperate to enable the second gear 34 to move vertically. At the same time, it can also rotate with the quill shaft 5. The quill shaft 5 is coaxially connected with a ring 35, which can limit the vertical downward displacement of the second gear 34, because the second gear 34 To be in a stable transmission state, a ring 35 is added to the quill 5, and the second gear 34 is placed on the ring 35 to ensure the stability of its meshing with the first gear 33. The second gear 34 The upper end is connected to a set of third spring 36 arranged outside the sleeve shaft 5, the other end of the third spring 36 is connected to the bearing seat 37 at the upper end of the casing 1, and the third spring 36 moves upward on the second gear 34 Energy is stored in the process. When the second gear 34 can move downward, the restoring force of the second gear 34 will push it to the initial position. It should be noted that the second gear 34 keeps rotating Yes, but the third spring 36 does not need to be rotated. We can connect a ring 35 plate at the lower end of the third spring 36, and set a thrust bearing between the ring 35 plate and the third gear to ensure both The main shaft 4 is coaxially connected to a shift lever 38, and the shift lever 38 engages a sheave 39 rotatably connected to the upper end of the box body 1, and the sheave 39 is coaxially connected to a sector gear 40, The sector gear 40 meshes with an end cam 41 that is arranged coaxially with the main shaft 4 and is rotatably connected to the upper end of the box body 1. The end cam 41 can drive the second gear 34 to move in the vertical direction and make the second The gear 34 is disengaged from the first gear 33. The rotation of the main shaft 4 will push the shift lever 38 to rotate. The rotation of the shift lever 38 drives the sheave 39 and the coaxial sector gear 40 to rotate. The sector gear 40 will push the end cam 41 to rotate. At a short distance, at the initial position, the concave end of the end cam 41 is matched with the second gear 34, and the first gear 33 and the second gear 34 are reliably meshed. Once the end cam 41 rotates, the convex end of the end cam 41 and the second gear 34 Gear 34 is meshed. At this time, the second gear 34 will be pushed upwards, causing it to disengage from the first gear 33. The first gear 33 does not drive the second gear 34 to rotate. At this time, the main shaft 4 continues to rotate. Adjusting the up and down position of the support plate 7 will not drive the sleeve shaft 5 to rotate. The lower end of the sleeve shaft 5 is threaded to fit a second screw 42 which is connected to the box. The limit rod 43 in 1 is matched to satisfy the limit rod 43 restricting the rotation of the second screw 42. The second screw 42 is provided with a groove along its axial direction. The limit rod 43 cooperates with the groove to restrict its rotation. At this time, the rotation of the sleeve shaft 5 only causes the second screw 42 to feed in the vertical direction, and the lower end of the second screw 42 is connected The outriggers 51, the outriggers 51 play the role of positioning support, making the device more stable and reliable. The rotation of the main shaft 4 will cause the supporting plate 7 to open upwards and the outriggers 51 to open downwards. Once the sector gear 40 is driven to engage with the end cam 41 , So that the second gear 34 moves upwards. At this time, the outrigger 51 is in the stabilizing device. If you continue to rotate the main shaft 4, the vertical adjustment of the support plate 7 can be completed. It should be noted that in the initial position, here The shift lever 38, the sheave 39, and the sector gear 40 play the role of delay. That is to say, after the main shaft 4 has rotated for a period of time, after the legs 51 and the support plate 7 are opened, the sector gear 40 is just in time with When the end cam 41 is engaged, the second gear 34 is disengaged from the engagement with the first gear 33. However, it should be noted that the adjustment range of the support plate 7 in the vertical direction cannot exceed, and the next concave end of the end cam 41 is the same as the current first gear. The matching position of the second gear 34 must be adjusted before the matching, otherwise, the second screw 42 and the leg 51 will be displaced in the vertical direction, which affects the stability.

[0044] The third embodiment, on the basis of the first or second embodiment, combined with the attached Figure 1-18 The said shrinking device includes two sets of two-way screw rods 45 which are longitudinally spaced in the box body 1 and are connected in the box body 1 in a transverse direction. The two-way screw rods 45 are provided with first screws with opposite rotation directions from left to right. The outer thread 46 and the second outer thread 47, the unthreaded part of the two-way screw 45 is rotatably connected to the bearing seat 37 in the box 1, and the first outer thread 46 is threaded with a first slider 48, The second external thread 47 is threaded with a second sliding block 49, so that the first sliding block 48 and the second sliding block 49 can only move laterally along the two-way screw 45, because the first sliding block 48 and the second sliding block 49 All are rectangular sliders. When setting, an inverted groove with a "T" cross section is opened at the lower end of the box 1, and a matching guide rail is connected to the slider. At this time, the rotation of the two-way screw 45 will cause the sliding The block moves in the transverse direction. The lower ends of the first slider 48 and the second slider 49 are both hinged with a vertical rod 50, and the other end of the vertical rod 50 is hinged with a wheel 2 longitudinally. A connecting rod 52 is connected by coaxial rotation. The other end of the connecting rod 52 is hinged in the box 1 on the lateral center side of the two-way screw 45, that is, the other end of the connecting rod 52 is connected to the two-way screw 45. The lower end of the bearing where the rod 45 is located constitutes a link mechanism. When the first slider 48 or the second slider 49 moves toward the center of the bidirectional screw 45 where it is located, the wheel 2 is connected with it due to the existence of the link mechanism. The rod 52 is lowered or retracted, and a worm gear 53 is coaxially connected to the two-way screw 45. The two sets of worm gears 53 engage with a worm 54 that rotates longitudinally in the box 1, and the worm 54 is at the same end. The shaft is connected with a drive handle 55. Rotating the drive handle 55 can make the worm 54 rotate. The worm 54 drives the bidirectional screw 45 to rotate through its cooperation with the worm gear 53, thereby adjusting the position of the wheel 2. The first external thread 46 The slider is connected to the first motor 3, and the first motor 3 is connected to the controller. The first motor 3 and the rotating shaft of the corresponding wheel 2 under the slider are connected in transmission via a belt. The belt drives the wheel 2 to rotate so as to realize the function of movement. The slider here does not rotate and only moves in the lateral direction, so the transmission is reliable.
